State the determinants of selective attention. How does selective attention differ from sustained attention?
The determinants of selective attention are the following:
(i) The external factors: These are the features of stimuli such as size, intensity, shape, etc.
(ii) The internal factors: These are present within the individual and can be divided into motivational factors and cognitive factors.
Motivational factors represent our biological and social needs. Instances of the same are the drivers strictly following all the traffic rules.
Cognitive factors represent the interests, attitudes, and preparatory set. For instance, an average teenager would be more interested in watching a cricket match than reading a novel.
Selective attention differs from sustained attention as sustained attention is primarily concerned with concentration and refers to the ability to maintain attention on an object for even for a long duration. Contrary to this, selective attention is related to the selection of a limited number of stimuli from a larger group of stimuli.
